Doesn't look all that sophisticated to me. If you have a Android device, consider WiFi Analyzer. I use it and like it. It allows you to assign an alias name (such as "Chapel") to MAC addresses which makes it easier to interpret.

Another tool I like is Fing which allows you to look at the devices on the network. (What services is the ward computer advertising?)
